leakage around doors and fittings on microwave ovens.
Highly potent microwave energy created by domestic microwave ovens is capable of penetrating living tissue to a depth of approximately 1.18" (30mm). Microwaves may easily pass through porcelain, glass, ceramics and most plastics.
It is of critical importance that ALL microwave ovens are periodically checked to ensure that no damage or malfunction has occurred since the time your microwave left the factory. Microwave leakage around door seals, hinges and metal fittings is far from uncommon.
